Buy now, pay later: how BNPL works and the risks

How BNPL works

The CFPB defines BNPL as an installment loan that typically lets you buy something with little or no payment up front and pay the rest over four or fewer payments. Unlike a credit card, your creditworthiness may be evaluated each time you use it (CFPB ↗).

Plans may charge low or no interest; the FTC suggests asking whether there are interest charges or fees and whether payments are reported to the credit bureaus (FTC ↗). California’s regulator reminds shoppers that BNPL plans are loans with the obligations of loans (DFPI ↗).

The main risks

• Returns. Even if you return the item, you may need to keep paying the BNPL loan until the refund is processed (CFPB ↗).
• Collections. If you do not repay and the debt goes to a collector, it may be reported and hurt your credit scores.
• Autopay from a low balance. Payments are usually taken automatically; a payment that hits an empty account can trigger bank fees on top of the lender’s late fee.
• Stacking. Several small plans at once are easy to lose track of; the CFPB notes BNPL can tempt you to spend more than you would otherwise.

What changed in federal rules

In May 2024 the CFPB issued an interpretive rule saying some BNPL lenders must give credit-card-style dispute and refund rights. On May 12, 2025, the CFPB withdrew that rule (CFPB ↗). Today your dispute and refund rights depend mainly on the provider’s terms and on state law, so read the terms before you use a plan.

An example

Our arithmetic: a $240 purchase in four payments is $60 at checkout and $60 every two weeks. Three such plans running together mean $180 due on some paydays. Write the dates down before you add another plan.

BNPL is not a cash loan

BNPL pays a merchant for a purchase; it does not put cash in your account. If you need money for rent or a bill, compare cash advance apps, a payday alternative loan or an installment loan instead.

Before you click “pay later”

1. Check the late fee and whether a missed payment is reported.
2. Check the return and dispute process in the provider’s terms.
3. Make sure each payment date falls after a payday.
4. Ask whether you can pay from a debit card and switch off autopay if you prefer to pay manually.

Questions

Does BNPL affect my credit score?

It depends on the provider. Some check credit or report payments; an unpaid plan sent to collections can hurt your scores (CFPB).

Is BNPL interest-free?

Many pay-in-4 plans charge no interest if you pay on time, but longer plans may charge interest. Check the terms for each purchase.

What if I can’t make a payment?

Contact the provider before the date. Ask about moving the date or a payment plan, and turn off autopay from an account that will be short.
